2 Claims.

The invention relates to the manufacture of mattresses.

One object of the invention is to provide an improved method of makingmattresses of the type in which quilted pads form the top and bottom ofthe mattress and by which a strip of material which is secured to thepad outwardly of its inner liner and inwardly of the outer liner isfolded around the border-member of a springstructure and the fillingbeneath the pad to firmly retain the outer liner of the pad in itsnormal shape.

Another object of the invention is to provide an improved constructionof mattress in which a strip which is secured to the pad outwardly ofits inner liner is folded and secured around the filling under the padand a portion of the filling in the pad to effectively' securel the padand filling to the border-members of the spring-structures.

Other objects of the invention will appear from the detailedldescription.

|The invention consists in` the several novel features which arehereinafter set forth and are more particularly defined by claims at theconclusion hereof..

In the drawing: Fig. l isV a sectional View of.' a spring-structurewith. the filling thereon before the pad, is placed on the filling. Fig.2 is a section illustrating the quiltedv pad having a strip inserted inthe padding material therein around its border laid onthe filling overthe springstructure, before the pad is secured to the springstructure.Fig. 3 is a section illustrating the insert-strip of the pad lappedaround the border-strip `0f the spring-structure and extended around andsecured by staples before the pad is secured to the boxing. Fig. 4 is a,section illustrating a portion of the completed mattress.

In making a mattress in accordance with the present invention anassembled spring-structure is used to form the center of the mattress.This structure usually comprises top and bottom border helicals 20,helicals a extending between and connected to the ends or sides of theborderhelicals and springs 2l between and having their upper and lowerends respectively connected to the top and bottom helicals of thespring-structure, as well understood in the art. A lling 22 is rst laid,as illustrated in Fig. 1, over the top of the spring-structure, with itsmarginal portion 22a projecting outwardly sufficiently from theborder-members to provide a portion which can be inturned and foldedunder the `bordermembers 20 of the spring-structure. This filling 22usually consists of sisal and cotton both of the necessary thickness toadequately cover the Openings in the spring-structure.

A quilted pad is used to form the outer faces of the mattress and this`comprises an inner liner 23 of material such as muslin, an outer memberof ticking 24, and an intermediate layer of cotton, all of which arestitched together, as at 2B, and constitute a preformed pad. The innerliner terminates inwardly of the margin of the padding 25. The tickingforms the outer face of the mattress. The outer margin of the ticking 24is usuallyr hemmed, as at 21, for subsequentV connection to the boxingforming the sides and ends of the mattress. Along the entire margin ofthe quilted pad the filling 25 isA divided horizontally into inner andouter layers 25a, 25b by a strip 28 of cloth, such as muslin, which isstitched to the pad by a seam 29 inwardly of the margin of the pad. Theouter margin of the strip 28 normally projects outwardly from the marginof the padding 25 and the inner and outer liners of the pad. The strip28 is used to secure the pad over the filling 22 and to thebordermembers of the spring-structure, as hereinafter described.

The next step in making the mattress consists in securing the nlling andpad to the bordermembers of the spring-structure. The marginal portion22c of the filling 22, the layer 25a of the padding 25, and the strip 28are folded around the border-member 2U of the springstructure andstaples 3D are driven through the strip 28, layer 25a of the pad 25, andfilling 22 inwardly of the border-member 20. The staples pass throughthe portions of strip 28 above and below the border-member. During thisstapling the strip 28 is drawn tautly around the layer 25 of the paddingand the portion of the filling 22 around which it is folded to compressthem so that they will tightly secure the filling and inner portion ofthe pad around the border-member of the spring-structure. During thisstapling operation, the outer margin of the ticking 24 and the portion25b of the padding is turned upwardly so the staples can be driveninwardly of the border-member 20. This operation can be quickly effectedby a suitable stapling machine which is adapted to compress the stripand material within it around the border-member of the spring-structurewhile the staples are being driven. The strip 28 extends completelyaround the side and end margins of the mattress and the staples arespaced apart so they will secure the entire border of the pad andfilling to the spring-structure. This securely connects the lling andpad to the border-members so that the border will conform and remainconformed to the borders of the spring-structure. A n important resultfrom the use of a strip interlaid in the padding of the quilted pad isthat the tension of the strip 28 is applied to the pad outwardly of ytheinnerliner, so the outer portion of the pad will be better held in shapethan when the margin of the inner liner is used for.

that purpose. When one face of the springstructure has been assembledwith the filling and pad in this manner, the spring-structure isinverted and the lling and pad' are assembledin the same manner to theother face of the springstructure. l

When quilted pads and fillings have been secured to both faces of themattress, a preformed box-border comprising an outer strip 32 ofticking, an inner liner 33, and a filling 34 of felt, which have beenstitched together, is fitted around the sides and ends of thespring-structure. The edge of the outer strip 32 is usually hemmed, asat 35. Next, the hemmed edge 21 of the ticking 24 of the quilted pad 24and the hemmed edge 35 of the ticking 32 of the boxborder are sewedtogether in a tape-edge stitching machine with a tape 36 around the seamto complete the mattress. In securing the boxborder between the top andbottom of the mattress, the springs 2| are compressed to a certaindegree so they will properly support the top of the mattress.

The invention exemplifies a method of making mattresses in which amarginal strip is interlaid with the padding of the quilted pad andsecures a portion of the padding in the pad over the lling under thepad, and is folded around the border-member of the spring-structure bystaples, so that the strip will hold a portion oi the padding of the padunder the strip and over the border-member by said strip. The inventionalso exemplies a mattress in which a strip interlaid in the padding ofthe pad secures the padding around the border-member of thespring-structure and exerts a pull onv the pad outwardly of its innerliner. This strip aids in keeping the ticking-member 24 and the paddingthereon more nearly taut than when only the inner liner is used tosecure the pad to the border-member.

The invention is not to be understood as restricted to the details setforth, since these may be modified within the scope of the appendedclaims, without departing from the spirit and scope of the invention.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent is:

1. A mattress comprising, a central springstructure including abordermember; a filling over the spring-structure having its marginsfolded around the border-member; a quilted pad over the lling comprisingan inner liner, an

outer ticking sheet and padding all stitched together separately fromthe lling; a strip having vits inner margin interlaid in the padding of,

and secured only to, the pad, the underlying portion of the paddingextending over the lling above the border-member, the strip extendingover said underlying portion of the padding and being folded around andunder the lling around the border-member; means inwardly of theborder-member extending through the strip above and below theborder-member, the underlying portion of the padding, and the filling,and terminating at the strip, said means securing said strip to hold thepad taut over the lling; and a box-border secured to the ticking sheetof the pad, the portion of the padding overlying the strip beingconfined against the strip by the connection between the pad and thebox-border.

2. A mattress comprising, a central springstructure including aborder-member; a lling over the spring-structure having its marginsfolded around the border-member; a quilted pad over the lling comprisingan inner liner, an outer ticking sheet and padding all stitched togetherseparately from the filling; a strip having its inner margin interlaidin the padding of, and secured only to, the pad, the underlying portionof the padding extending over the filling above the border-member andbeing folded around and under the filling around the border-member;staples inwardly of the border-member extending through only the stripabove and below the border-member, the underlying portion of thepadding, and the filling, the staples securing the strip to hold the padtaut over the `filling; and a box-border secured to the ticking sheet ofthe pad, the portion of the padding overlying the strip being confinedagainst the strip by the oonnection between the pad and the box-border.
